DETACHABLE-LINK CONNECTION FOR VALVES.

Application filed February 17, 1912.

To all whom it may concern:

Be it known that I, EDWARD DIEFENBAGH, a citizen of the United States, residing at Huntington, in the county of Cabell, State of Test Virginia, have invented certain new and useful Improvements in Detachable-Link Connection for Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in valve connections forsanitary drinking fountains.

The principal object of the invention is to provide a novel detachable link for connecting the valves of the fountain.

Other objects and advantages will be ap parent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a side elevation of my improved device showing the same in applied position. Fig. 2 is a detail perspective view of the detachable link employed between the operating arms of the valves.

Referring more specifically to the drawings, in which similar reference numerals designate corresponding parts throughout, 1O designates a suitably supported supply tank. This supply tank communicates with a relatively small auxiliary tank 13 and eX- tending downwardly from the auxiliary tank is a supply pipe 11 the lower end of which terminates-in a nozzle 17.

Below and above the auxiliary tank 13 are the cut oil valves 22 and 25 of the turn plug type having their stems provided respectively with the levers 24: and 30. The levers are connected by a detachable link which will now be more particularly described.

In order to provide means for operating these valves simultaneously I provide a link 31 which is pivotally mounted at one end to the lever 21 intermediate the length of the latter and which is provided at its upper end with a keyhole slot 32 the lower end of which is enlarged to permit the passage of the head of a headed pin 33 carried by the free end of the lever 30. Pivoted upon this link 31 intermediate its length, is a latch member 34 the upper end of which is provided with a cam face 35 adapted to engage Specification of Letters Patent.

against the headed pin 33 and force the same into the reduced end of the slot 32 when the link 31 and the latch 31 are in parallel superimposed position as shown in Fig. 1, thus locking the link against disengagement "from the lever 30. The lower end of the latch 31 is provided with a spring pressed pin 36 1 for engagement in an opening 31' in the link 31 to normally hold the same against movement with respect to the link 31.

To permit the two valves to be placed in either opened or closed position, the link connecting the valve levers may be readily removed by pulling the pin 36 from the opening 31 and swinging the lever or latch 34 to one side. This releases the end or cam face 35 from beneath the head oi? the pin 33, when the lower end of the link section 31 is moved upwardly with the lever 24, thus bringing the circular portion of the keyhole slot in position to permit the link 1 to be disengaged from the pin The link 31 thus remains attached to the arm 24.

It will of course be understood that minor changes in the details of construction, may be made if desired without in the slightest degree departing from the spirit of my invention.

\Vhat I claim is z The combination with a pair of valve arms and headed pins carried thereby, of a detachable connecting link comprising a pair of levers pivoted together, one 01 said levers being longer than the other, the longer lever having a circular opening in one end for the reception of one of the said pins and a key hole slot in the other end for the reception of the other pin, said longer lever havinga second circular opening adjacent the first named opening, the shorter lever having a cam at one end for engagement with the second named pin, and a spring pressed pin mounted on the opposite end of the shorter lever for engagement in the second named circular opening of the longer lever simultaneously with the engagement of the cam with the second pin to detachably hold the levers in superposed relation and in engagement with said pins.

In testimony whereof, I affix my signature, in presence of two witnesses.
